Question

Which of the following is the final equation for refining zinc metal from its ore?

A. 2ZnS + 3O2 + C → 2SO2 + 2Zn + CO2
B. 2ZnS + 3O2 + C → 2SO2 + 2Zn + CO
C. 2ZnS + 6O2 + C → 2SO2 + 2Zn + CO2
D. 4ZnS + 3O2 + C → 2SO2 + 4Zn + CO2

Answer 1

@dtan5457 Do you know this one?

Answer 2

Are all the equations balanced? If not, I'm assuming it's the one that is balanced, as a reaction can only take place if so

Answer 3

@dtan5457 yeah and i think it's A

Answer 4

yeah, A is balanced.

Answer 5

but they're all balanced...

Answer 6

Look at the second one, the only change is that CO2 is missing the 2 from answer A. It is not balanced.

Answer 7

oh ok thanks
